SYSMBOLS TO ALERT STAFF OF HAZARDS OF CHEMICAL

Question 2: BRINE TANKS

Answer:

CREATE SOLUTION TO REGENERATE THE SOFTNER (EXCHANGE THE MAGNESIUM AND

CALCIUM IONS FOR SODIUM IONS)

Question 3: IFU

Answer:

INDICATES INSTRUCTION FOR USE

Question 4: BACK FLOW PREVENTION DEVICE

Answer:

TO KEEP WATER FROM FLOWING BACKWARD INTO THE INCOMING WATER SUPPLY. THIS

INTURNS PREVENTS ANY CONTAMINATION TAKEN OUT BY THE WATER TREATMENT SYSTEM

FROM GETTING INTO THE FEED WATER

Question 5: REJECT WATER (CONCENTRATE)

Answer:

THE WASTE OR REJECT STREAM THAT IS SENT TO THE DRAIN ALONG WITH THE SOLUTES

REMOVED BY RVERSE OSMOSIS

Question 6: MEMBRANE FILTERS

Answer:

ARE WATER TREATMENTR CARTRIDGES CONTAINING THIN MEMBRANES WITH PORES OF

SPECIFIED SIZE.

Question 7: ACTION LEVEL

Answer:

THE ACTION LEVEL FOR TOTAL CHLORINE IS 0.10 PPM WHICH NECESSITATES CORRECTIVE

MEASURE TO BE TAKEN TO RESTORE WATER TO A SAFE RANGE (0.00 PPM - 0.09 PPM)

Question 8: FREQUENCY TOTAL CHLORINE TESTING

Answer:

FOR ROUTINE DOCUMENTATION PRIOR TO FIRST PATIENT AND EVERY 3-4 HOURS DURING

TREATMENTS

Question 9: HYDROMETER

Answer:

device used to measure specific gravity of acid concentrate after mixing . the specific gravity must be +/-2% of expected range after mixing acid concentrate

Question 10: DRY ACID DISSOLUTION UNIT (DADU)

Answer:

DEVICE USED TO PREPARE ACID CONCENTRATE SOLUTION FROM A DRY POWDER AND RO

WATER AT A CENTRAL LOCATION

Question 11: WATER SOFTNER

Answer:

softens hard water by taking out some of the magnesium and calcium that form the scale

Question 12: PERCENT REJECTION

Answer:

provides an indication of how effective an RO machine is, must be 95% when installed and when membranes are changed, action must be taken when there is a radical change in rate

Question 13: INDIRECT FEED

Answer:

A WATER SYSTEM DESIGN IN THE FACILITY THAT HAS HOLDING (STORAGE) TANK

Question 19: DELTA PRESSURE

Answer:

Pressure difference pre and post filter, limit 10psi

Question 20: EMPTY BED CONTACT TIME (EBCT)

Answer:

TIME DURING FEED WATER MUST REMAIN IN CONTACT WITH CHARCOAL LONG ENOUGH TO

ALLOW ADEQUATE REMOVAL OF CHLORINE AND CHLORAMINES. LENGTH OF TIME WATER IS

EXPOSED TO CARBON. AAMI ALLOW 10 MINUTES.
